1. Field of the Invention
The present invention relates generally to pickup box lights and more specifically it relates to a tailgate controlled light system for automatically illuminating the interior of a pickup box upon opening of a tailgate.
2. Description of the Related Art
Pickup box lights have been in use for years. A conventional pickup box light is mounted to the upper rear portion of the cab of the pickup and has a manual control switch for users to operate that controls the light.
The main disadvantage of conventional pickup box lights is that they do not automatically operate to illuminate the interior of the pickup box during loading/unloading of cargo. Another disadvantage of conventional pickup box lights is that require the user to physically locate and manipulate a switch to turn the lights on. Another problem with conventional pickup box lights is that when a pickup box cover is utilized the light is blocked by the cover if the cover is closed.
Examples of patented devices which may be related to the present invention include U.S. Pat. No. 5,495,400 to Currie; U.S. Pat. No. 6,238,068 to Farmer, Jr.; U.S. Pat. No. 6,431,717 to Anderson et al.; U.S. Pat. No. 5,795,051 to Galanski; U.S. Pat. No. 4,745,525 to Sheehy; U.S. Pat. No. 5,258,893 to Finneyfrock; U.S. Pat. No. 6,116,761 to Munsey; U.S. Pat. No. 4,839,629 to Brown; U.S. Pat. No. 4,818,006 to Arndt; U.S. Pat. No. 6,000,821 to Beliakoff; and U.S. Pat. No. 5,144,538 to Harris.
While these devices may be suitable for the particular purpose to which they address, they are not as suitable for automatically illuminating the interior of a pickup box upon opening of a tailgate. Conventional pickup box lights do not allow for automatic operation thereof based upon the opening of a tailgate.
In these respects, the tailgate controlled light system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of automatically illuminating the interior of a pickup box upon opening of a tailgate.
In view of the foregoing disadvantages inherent in the known types of pickup box lights now present in the prior art, the present invention provides a new tailgate controlled light system construction wherein the same can be utilized for automatically illuminating the interior of a pickup box upon opening of a tailgate.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new tailgate controlled light system that has many of the advantages of the pickup box lights mentioned heretofore and many novel features that result in a new tailgate controlled light system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art pickup box lights, either alone or in any combination thereof.
To attain this, the present invention generally comprises a light unit attachable within a pickup box, a control switch electrically connected to the light unit and attachable within the opening of the pickup box, and an override switch electrically connected to the control switch and to the vehicle power supply. The control switch is positioned to be depressed by the tailgate when closed thereby terminating power to the light unit. When the tailgate is opened away from the control switch the light unit is activated with power. The override switch is used to terminate power to the light unit regardless of the position of the tailgate.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
A primary object of the present invention is to provide a tailgate controlled light system that will overcome the shortcomings of the prior art devices.
A second object is to provide a tailgate controlled light system for automatically illuminating the interior of a pickup box upon opening of a tailgate.
Another object is to provide a tailgate controlled light system that may be utilized within various brands and designs of pickups.
An additional object is to provide a tailgate controlled light system that may be installed upon an existing pickup as an aftermarket item or installed during the manufacture of a new pickup.
A further object is to provide a tailgate controlled light system that increases the visibility within a pickup box for loading/unloading cargo, particularly where a pickup box cover is secured over the box.
Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
B. Light Unit
As shown in
The light unit 30 is preferably positioned beneath a bedrail of a pickup box 12 as best illustrated in
C. Control Switch
The control switch 40 is electrically connected to the light unit 30 as shown in
D. Override Switch
The override switch 20 is electrically connected to the control switch 40 for allowing override control over the present invention. The override switch 20 allows for a user to terminate power to the light unit 30 regardless of a position of a tailgate 14. The override switch 20 is also electrically connectable to a power source as shown in
As shown in
In use, the user opens the tailgate 14 of the pickup to load/unload cargo. When the tailgate 14 is partially opened as shown in
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed to be within the expertise of those skilled in the art, and all equivalent structural variations and relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
